Hello, I am trying to mesh a multi-element airfoil with fully unstructured with tetra mesh, the problem that I have is that at the trailing edge it seems like if there would be a leakage of the mesh inside of the airfoil. The distance between the upper line and the lower line of the airfoil at the trailing edge is really small so I do not know if that has some influence. Another thing that I have found when I did the mesh is that in the model tree in the mesh part the lines and the curves in geometry do not match one to the others and where they do not match is where the leakage appears, I would be really thankful if someone could help me with that.

Also I would like to say that a video tutorial like the hexa on youtube about how to do a hybrid mesh using the 2d Blayer could be really useful for lot of people.

Here you can see what is happening to me, the elements cannot represent properly the geometry, I don't know if this is because any kind of tolerance of because of the size of the element. That mesh is patch dependent mesh. Thank you
